Of course most hunters know that energy is measured by bullet diameter X bullet weight X bullet volocity X distance.

I don't see bullet diameter ,or distance mentioned in any of the calculations below.

Formula used:
Energy = .5 * weight * velocity^2 / 7000 / 32.175

Where weight is in grains, and velocity is in feet/second.

7000 is grains per pound, and 32.175 is acceleration due to gravity.

It can be re-written:
Energy = weight * velocity^2 / 450450

Kinetic Energy (KE) = 1/2 MV2

Velocity (V) is usually given in feet/second (fps) and mass (M) is given in pounds, derived from the weight (W) of the bullet in grains, divided by 7000 grains per pound times the acceleration of gravity (32 ft/sec) so that:

Kinetic Energy (KE) = W(V)2 / (450,435) ft/lb
